Specification oi Letters Patent.

To all 'wiom it' may concern Be it 'known'that l, STEWART lVAinNc, a citizen of the United States, residing at Evanston', in the county o Cool; and State of l'llinfois, have invented certain new and useful Improvements in Paperfiinding Mechanism, of which the following is 4a specification.

This invention relates to mechanism toi:

winding strips of paper or .similar material into rolls.

' One of the objects of the invention is to rovide mechanism so that the strips may 'e wound into suitable rolls without the use of a core or central mandrel upon' which the strips are woini'di The machine to which the invention more particularly.7 relates ,is ot that type illustrated anddesci'ibed in Letters Patent No'. 999,352, Igranted to ine August 1, 1911. In that machine mechanism is provided for winding strips of. paper into rolls without 'soA the use of the central core or mandrel. And the. mechanism herein illustrated and 'de- .scribcd is adapted to more etlectirely carry 'on' the rolling process, ,particularly .when

the end ot thestrip is caused to curl upon itself and forni the central turniot the roll. It has been found that, wit-h t-he mechanism described in said patent,

,of the `strip would become bent and crinkled somewhat before it -Would lgegiiito roll properly.

` And to avoid this is one ofthe objects ofthis invention.

In the accompanying dra.wings,Figiire l is a Vertical transverse ingineclanisni which embodies features 4of my invention. Fig. 2 is aperspectiv'e view of a nienibcr used in the mechanism to .proper1)1 guide the end ofthe strip in order to form the lli-st turn of therolland to assist in forming'subsequentturns Fig. 'B'isa detail view of a portion of two of the rollormi'ng rotary .members The machine descr'bed in the patent ie`,.

'And at times the end' section of a. wind i'ollr -snugb7 '.and `properly rollers insuccessio'n as the strip end comes in contaet with the roller so as to form a suitable central tinn upon which the relat'eiitcd Dee. 16, .$513.

mai-nder of-thc roll is wound. The inctlia- -nisin Vherein shown. is ot the sani-:i general tnie;-l.iiit herein one of the rollers, shown in said patent is replacedhy a stationari" guide member along; thesiirfac'cs ol'wliicli the end ot the strip is pushed; and these surfaces, in conjunction with the periphcries of the rollers, cause thecnd .of the sl rip to curl upon itself and make a suitable tuin for the center of tlie'roll. As a result of this arrangement there is 'no bending or.

crinlling: of the end of the strip, and the central turn of the rollA is as suitabli7 woi'ind as ain,7 other turn. l

The roller mechanism comprises four rollers'l, 3 and 4. These rollers .are

composed of the central portion or shafts 5, G, and S, each haring a series oi'? annular ribs oi-.lianges 9 thereon. rollers l. and 2 are jonrnaled in hearinfgjs fixed to the frame 10 ot thev 'mat-bine; and the shafts of" the rollers 3 and -4 are jour- Iialcd in bearings in upright pieces:4 3.1. which are piroted to the ti-'aineworlc'at their lower ends. These iiprights are )'ieldingi'li' held in place by means of the link llh thi` a'rni'fllb piroted to said link and to the framework, the link ll, and the spring ullY'shOWn and described in said patent.

`as is fully described in Saidpatent. u

.The paper strip ,12 is fed, hyfmcans :of

ondai)7 feed rollers 13 and 14.

13 and 14 are'suitably nioniitetl in hearings against the 'roller 14' by means of a spring 15 at each' end of the roller, compressed be-4 tween a collar 16, fixed to an adjustable screw 17, and a slidable block 18 which presses against the end of the shaft of the roller 13.- The screw 17 A is threaded into the fixed block 19. The rollers 13 vand 14 also have annular'ribs or flanges20 on the shaft portions, andv between these flanges the guide member 24 the edges,.24a of the member are upturned so as to revent the ends of the' paper strips striking against the edges.

.- The pa er strip which is to be formed into a roll is orced along these guides 21 and 22 into the roll-'forming space, and as it passes into this space is bent downwardly by the guide 24, as indicated, and passes over until it comes'in Contact with roller 3e The -flanges of each of these' rollers run between the flanges vof the adjacent roller so that the end of the -strip cannot pass between the '-two rollers, except in case of the rollers 1 and 2. Also each of the flanges on the rollers 2, 3 and 4 has on its periphery a plurality of notches 25; and as the end vof the aper strip comes in contact with these gauges the end is forced, by means of these notches, in the direction of rotation o'f the roller.

The rollers may be rotated by any suitable means.. The roller 2 may be rotated by means of the gear wheel 26 fixed to the shaft ofthe roller, the 'idle gear wheel 27, and

' the gear wheel-28 fixed to the shaft ofthe roller 14; and the gear wheel 28 may be rotated in anysuitable manner.- In asimilar wayv roller 1 may be rotated. Roller 4 may be rotated by means of a belt v29 passing over a. grooved pulley 30 fixed to the end of shaft 8 and' operated in any .suitableV manner; and roller 3 may be operated-'1n a similar manner.

The roll-forrning rollers are all rotated in the same direction.` Inthis instance the direction of rotation, 'as' indicated by the arrows, is counterclockwlse .(Fignll). As

V the end ofjthe strip comes in contact in the manner herein'before described with the roller 3, 'the end is carried upward in contact with the roller 4, thence backward in contact -with the roller 2,' thence in contact with the curved upwardly extending projections 31 on the guide member 24, and thence downward along'the surface of these pro# jections 'until it.comes in contact .with the strip itself and is thus forced continuously around, forming perfect turns. As the process continues the rollers'- and 4 are forced,

by the paper roll 32, outwardly so as to en! large as needed the space in which the roll is being formed. lVhen the roll is of the required size, suitable mechanism is set in operationA in la manner fully described in said atent, and the knife 33`is forced down war ly'severingv the strip; the rolling process is conti-uned until the' projecting end strip is wound around the roll; the mecha nisni then forces outwardly rollers 3 and 4 and thecompleted roll falls to a suitable receptacle. The severed end of the strip is then vforced inwardly between the two sec,

'ondary feed rollers and the process is continued.

By suitably positioning the roll-forming rollers, and the guide member 24, and by suitably shaping the surface ofthe guide member 24, the roll. may'jthus be formed without the use of a central coreor mandrel, and without bending or crmkling any4 et .the turns of the roll.

Byv arranging to rotatey the roll-forming rollers-'at a somewhat greater rate than that of the'prim'ary feed rollers, shown in said patent, any slack that may accumulate between the time of finishing one roll and be ginning the next 'will be taken care of.

I claim aslrny invention:
